//determine if they need to see the form or not
if (!$_POST)
{
//they need to see the form, create form block
$display_block = <<<END_OF_BLOCK
<form method="POST" action="{$_SERVER['PHP_SELF']}">
<p><label for="email">Your E-Mail Address:</label></br>
<input type="text" id="email" name="email" size="40" maxlength="150" /></p>
